贵阳高校新生睡眠质量与体重指数的相关性分析

目的 研究高校新生的睡眠质量及体重指数现状，探讨二者的相关性。方法 采用多阶段分层整群随机抽样的方法，应用匹兹堡睡眠质量指数量表和自编调查问卷，对12323名新生进行问卷调查，并测量身高、体重。结果 体重过轻、正常体重、超重、肥胖的检出率分别为21.75%、65.70%、9.15%、3.42%，性别、家庭所在地、学校类型及午睡习惯不同，BMI得分差异均有统计学意义；平均睡眠时间为（7.03±1.04）小时，PSQI得分为 0~17 分，总均分为（5.31±2.63）分，睡眠障碍检出率为18.32%；不同BMI分组下睡眠障碍检出率差异有统计学意义，肥胖组的睡眠障碍检出率最高；多因素logistic 回归分析显示，性别（OR=0.707, 95%CI:0.650~0.768）、家庭所在地（OR=1.151, 95%CI:1.053~1.256）、肥胖（OR=1.458, 95%CI:1.187~1.790）、午睡习惯（OR=1.380, 95%CI:1.251~1.522）是新生睡眠障碍的影响因素（P值均＜0.05）。结论 高校新生睡眠质量问题与肥胖关系密切，合理的体重及良好的睡眠习惯控制有助于改善睡眠质量。

Correlation analysis of sleep quality and body mass index of college freshmen,Guiyang

Objective To study the current situation of quality and body mass index of freshmen, and to explore the correlation between them. [WTHZ]Methods With the method of multi-stage stratified cluster random sampling, the Pittsburgh sleep quality index scale and self-compiled questionnaire were used to conduct a questionnaire survey among 12323 freshmen, and then the height and weight were measured. [WTHZ]Results The detection rates of underweight, normal weight, overweight and obesity were 21.75%, 65.70%, 9.15% and 3.42%, respectively. There were statistically significant differences in BMI score with respect to gender, family location, school type and nap habits. The average sleep time was (7.03±1.04) hours. The PSQI score ranged from 0 to 17 points, and the mean score was (5.31±2.63). The detection rate of sleep disorders was 18.32%. The differences in the detection rate of sleep disorders in different BMI groups were statistically significant. The detection rate of sleep disorders was the highest in the obesity group. Multivariate logistic regression analysis showed that gender(OR=0.707, 95%CI:0.650-0.768), family location(OR=1.151, 95%CI:1.053-1.256), obesity(OR=1.458, 95%CI:1.187-1.790) and napping habit(OR=1.380, 95%CI:1.251-1.522) were the influencing factors of sleep disorders of freshmen (P<0.05). [WTHZ]Conclusion Sleep quality of college freshmen is closely related to obesity. A reasonable weight and good sleep habits can help to improve the quality of sleep.
